| 中文摘要 | water insoluble poly(epsilon-caprolactone) (pcl) was micronized into narrowly distributed stable nanoparticles. the biodegradation of such pcl nanoparticles in the presence of the enzyme, lipase ps, was monitored by using laser light scattering because the scattering intensity is directly related to the particle concentration. the pcl and enzyme concentration dependence of the biodegradation rate supports a heterogeneous catalytic kinetics in which we have introduced an additional equilibrium between the inactive and active enzyme/substrate complexes. the initial rate equation derived on the basis of this mechanism was used to successfully explain the influence of surfactant, ph and temperature on the enzymatic biodegradation. our results confirmed that both the adsorption and the enzymatic catalysis were important for the biodegradation of the pcl nanoparticles.
